PLATEN-Tnnn MECIIANISII.

T all whomitmay concern: Y

Be it know'n that I, Aires H. HAWLEY, acitizc-.n ofv the UnitedStates, residing at' Terre Haute, in the county of Vigo and. State of Indiana, have invented certain new and useful Improvements in Platen-Feed Mechanism, of which the following is a specification.

ln thev operation of listing machineswherein it is usual to employ a printing andfeed platen, itis common also to utilize suitable means to impart single, double, or triple spacing movement to the platen for correspondingly spacing the items listed. Likewise it is customary to employ centering means such as a spring-pressed rollei` to hold the platen at uniform adjustments.

In certain establishments a payroll system is used wherein wage receipts to be signed.

by paid employees'are printed' on a scored web, each receipt being supplied with the einployees name, number and department, by ali-addressing orflike machine, and the amount of salary or wages is printed or filled in by a typewriter or adding machine.' Then each stripof receipts for a department is delivercd to the foreman ordinarily who in lturn tears off each receipt for signature by the employee and return to the paymaster. The receipts areordinarily of some size,

necessarily, and even where only an inch wide they require greater movement for spacing the 4amount'items supplied by the' adding machine than is obtained by the customary space feed instrumentalities While the presenti mechanism involves special platen feed mechanism, for effecting the unusual spacing movement of the paperweb of receipts, or any 'like web, and is ap= plicable to adding, typewriting, and accounting machines generally, an especial objectin view lhas been toadapt certa-in platen feed mechanism of what are known as international pay roll,-and linternational adding' manually operable, saidgearing affording a most efficient mode of mcreasmg or reducing g y Patented July 25,1916.

the extent of movement of the platen,and

doing so with the required expedition and 'accurac operating machines ofthe class improved upon, invention, reference is to be had lto the following description ,and the accompanying drawings, in which :---A

Figure .l is a fragmentary plan view ofthe rear portion of an adding machine equipped' with.' platen feed -mechanism in accordance with the invention. Fig. is a side view of the saine. Fig. 3 isa rear elevation. Y Fig. fl is a sectional view showing in elevation the ratchet `feed devices and the centering pawl.

, a desiderat'um of importance in fast eej For a full :understanding of the present Fig. 5 is a horizontal sectional View taken about on thev line 5-'5 of Fig. 2. Fig. 6 is a section taken about on the line 6 6 of Fig. 5.

Referring to thedrawings and especially .to Figs. l to 3 inclusive, a conventional adding machine is partly illustrated, the samebeing supplied with listing mechanism including typecarriers 860 controlled from the keys 121i of the keyboard 124. This adding machine is operated inthe customary lway by' the actuator 501 in the forinof a handle, or a motor drive may be employed, this being immaterial. At the rear of the machine is mounted a laterally sliding carriage having the 'platen '1905 mountedthereon, the latter ,being supported bythe side plates 1903 of' the carriage, as will be more fully described hereinafter; Since'the'mounting of the earriage supporting the platenlQO is not material to the invention, 4asrespectsthe slidablc action, the same will not be described. vIt

will be noted,-however, byA referenee-torFig.`

1 that a paper web R feeds upward over the laten1905 from a roll supported on suitable brackets S, and this web is scored 'so as to be divided into receipt sections ofa coiiventional form used in many estab'lislmien'ts havingl'arge pay-rolls. yThe listing mechanism is adaptedto print directly upon. the Y receipt sectionsy of the web Rias illustrated 'in g Fig. 1, and while a wide carriage platen mechanism is shown it is to be'u'nderstoo'd that the invention is equally adapted 'tor use in connection withfeed mechanism for narrower platens fixedlysupported on themal lica `chine, lthe feature of slidability `fnothaving 'i any thing to do with the essence of the in vention,

The feeding .mechanism will now he Set forth in detail, by reference to Figs. Q to G inclusive.

in .l5-igt` 5 it willhe seen that the platen shaft passes through a sleere fi. n'iounted rotatively in an opening in the side plate '1.903 of the carriage and. said sleeve forms a hearing for said shaft and also forms the axis of the feed pawl arnr 1922. Pinned or otherwise fixed to the sleeve A is the ratchet Wheel l engageitl by the spring controlled pand 1908', the )and being adapted tomove with the. arm w22 aforesaid which arm is operahle by a driving link 1908. A spacing collar 'l fitted about the sleeve A prevents lateral movement ot the sleeve in one direction, the huh of the platen performing the same function as to possible movement in. the opposite direction.

As seen in Fig. 4.-, the cent-erine datent i" employed, the same being pirotallv mounted on the plato i903 and haring the roller t? engageiible with the teeth ot the ratchet Wheel il, a suitable spring P acting to maintain said engagement in a well linea n manner.

The link 1908, see Figs. il and 3, extends downwardly and has an adjustable conneetion at 1908 with a rocher arm 2081 which is mounted upon the rock shaft T supported in bearings in the side plates 1903 of the carringe. The. rock shaft T is designed to he operated on each operation ot the machine oi' Whichthe present platen feed mechanism forms a, part, but the actuating means for said shaft is not material and therefore only incompletely illustrated as a hail on the shaft T, which hail is engaged by a. driving har V adapted to have motion imparted thereto from any driven part oF the. machine actuated incident to each operation of the latter. Longitudinalmovement of the bar V rocks the shaft T andcorrespondingly rocks the arm 2081 upward, motion being thus imparted to the ratchet Wheel i3 through the driving parte .i908 and paul 1908. A shift ing oi the coimcction 19054", employed interi mediate the parte i908 and 520551 to earry said connection to any of its positons designated m, 9,1, e, in Fig. 2,"Will effect single, douloleor triple spacingmovement of the ratchet B ander normal conditions.

Referring now to Fig. 5, it is to he noted that the sleeve il. carries in addition. to the ratchet B a transmission gear C adapted to mesh with a corresponding gear E on a trunnieu I fixed to the plate 1903. The gear E is carried by a sleeve J which in turn carries a sleeve K rotative with the sleeve J hut slidable lengthwise ofthe latter, owing to the provision of the key M on said sleeve I engaging in a hert il formed in the sleeve J. The sleeve K carries a gear G of relatively ineens@ large diameter adapted to mesh with a gear H of relatively small diameter mounted upon a bushing N pinned or otherwise fixed to the platen shaft 2095; and the gear F carried by the sleeve J is adapted also to mesh with a gear D on the bushing N. The gears C, D, are of equal dian'leter, and gears E, F are ot' equal dian'ieter as seen from thedrawf ings, and provision is made by novel means to hold the sleeve K in either of two positions, namely with the gears C andD engaging the gears E and F respectively, and

`with said gears disengaged in sucha manner that the gear (i meshes with the small gear H. The holding means for the sleeve K for the above purpose includes a springpressed hall J #cated in an opening inthe sleeve I( and adapted to engage in either of two recesses J" iin-med in the periphery of the sleeve T. To prevent displacement of the sleeve K from the sleeve .T a screw 2 is screwed into the outer end of the stud I, and to likewise hold the key M and the hall J against displacement a ring L encireles 'the sleeve K, is recessed to receive the T-shaped head of the key M and the spring enacting with the ball J and located hetween the gi-.iars 'F and G (see Figs. 5 and 6).

The gearing above described permits of differential driving of the platen .by the driving connections above set forth, the operation of the parts being substantially as follows. The normal operation of the platen feed mechanism .for ordinary purposes will involve the adjustment of the connection 1908, seen in Fie'. 2, in any one of the positions .'n, y, e. Operation of the link 1908' under such conditions, with the parts acljusted also as seen in Fig. 5, will cause .partial rotation of the ratchet B and a. come sponding extent of rotation of the platen 1905. motion being trausu'iitted to the latter through the sleeve A., gear C, gear E, gear F. gear D and shaft 2095 to which the gear D is fixed.

For the unusual spacing of the printed .items as required for the printing of the receips R. in Fig. l, the connection 1908 of the link 1908 will he adjusted as seen in Fig. 2. The sleeve K which is formed so as to provide a knurled handle seen in Fig. 3, is then pulled outward so as to shift the gear' F from its engagement with the gear D and the gear G- into engagement with the gear H. By this adjustment the motion of the larger gear Cis transmitted to the smaller gear H, the drive being as follows: sleeve A through gear G to gear E, sleeve J to sleeve K, gear Cr to gear H, sleeve N to platen shaft 2095. It is to be noted that the feeding ratchet B and consequently the centering means in cludiug the members l? and O do not act directly on the platen to locate the same, but indirectly, such action making possible the advancing of the platen a fractional number -ofregular divisions such as isrequired in the ordinaryuse of the machine, as for single, double and triple spacing.

By reason of the peculiar construction and operation ofvparts as-hereinbefore set forth,l

a large numberof 'the `usual driving instrumentalities'required for platen feed mechani'smsV such as now used in many different formsof accounting machinesmay be retained-"gwhen the mechanism is modified to secure"Qi-the advantages. of the construction and operation yhereinbefore presented.

It isto be understood that .I do not Wish to be limitedpto .the `particular differential -gear devices employed .as hereinbefore de scribed,., however, because the differential rdriving of the vplaten may be effected by Having thus .v described the invention,
